I have a sort of a light clicking rustling sound when operating the clutch on my 5th gen. It has only done 8k miles and only appears when holding at the lights ect. From memory i had a 5th gen years ago and that one had the same sound as well, if i move the engaged clutch lever in and out while stopped just before it bites then i can hear it. It never seemed to do any harm,just wondering why it does this?
Same as my Gen 5 most likely its the airbox flapper, funny thing was on my previous Gen 6 it was more a faint popping noise.
